Item 1.  Business

     The Navistar Financial Dealer Note Trust 1990 (the "1990 Trust") was formed
pursuant to a Pooling and Servicing Agreement dated as of December 1, 1990 among
Navistar Financial Securities  Corporation,  as seller (the "Seller"),  Navistar
Financial  Corporation,  as servicer (the  "Servicer"),  and The Chase Manhattan
Bank (survivor in the merger between The Chase  Manhattan Bank and Chemical Bank
which was the survivor in the merger  between  Chemical  Bank and  Manufacturers
Hanover  Trust  Company),  as 1990 Trust  Trustee.  Wholesale  dealer notes (the
"Dealer  Notes") and security  interests in the vehicles  financed  thereby were
transferred  to the 1990 Trust in exchange  for three  classes of floating  rate
pass-through certificates (the "Investor Certificates") which were remarketed to
the public.  The Seller's undivided  fractional  interest in the 1990 Trust (the
"Seller Interest") is evidenced by a Seller Certificate.

     Additional Dealer Notes are sold on a daily basis by the Seller to the 1990
Trust to replace those Dealer Notes which have been liquidated or charged off as
uncollectible.  Accordingly,  the  aggregate  amount of Dealer Notes in the 1990
Trust will  fluctuate  from day to day as new Dealer Notes are  generated and as
existing Dealer Notes are removed.

     Under the terms of the  Pooling  and  Servicing  Agreement,  the  Seller is
required to maintain a minimum investment in the 1990 Trust (the "Minimum Seller
Interest"), a portion of which is subordinated to the Investor Certificates.  If
the amount of Dealer Notes in the 1990 Trust is less than the combined ownership
interest evidenced by the Investor Certificates and Minimum Seller Interest, the
Seller must transfer additional funds (the "Investment  Securities") to the 1990
Trust to  maintain  the Seller  Interest  at an amount not less than the Minimum
Seller Interest.

     On June 8, 1995,  the  Navistar  Financial  Dealer Note  Master  Trust (the
"Master Trust") was formed  pursuant to a Pooling and Servicing  Agreement among
Navistar  Financial  Securities  Corporation,   as  seller,  Navistar  Financial
Corporation,  as  servicer,  The Chase  Manhattan  Bank  (survivor in the merger
between The Chase Manhattan Bank and Chemical Bank which was the survivor in the
merger between Chemical Bank and Manufacturers  Hanover Trust Company),  as 1990
Trust  Trustee and The Bank of New York,  as Master  Trust  Trustee.  On June 8,
1995,  the 1990  Trust  issued  Class A-4  Certificates  in the amount of $207.9
million to the Master Trust which, in turn, issued Series 1995-1 Certificates in
the amount of $200.0  million to the public.  On August 19, 1997, the 1990 Trust
issued  Class A-5  Certificates  in the  amount of $200.0  million to the Master
Trust which in turn issued Series 1997-1 Certificates to the public. On July 17,
1998,  the 1990  Trust  issued  Class A-6  Certificates  in the amount of $200.0
million to the Master Trust which in turn issued Series 1998-1  Certificates  to
the public.

     The 1990  Trust is the  active  trust  and will hold the  Dealer  Notes and
certain related assets until the termination of the 1990 Trust.  The termination
of the 1990 Trust will occur upon the  repayment of the one  remaining  class of
Investor  Certificates issued in 1990 (Class A-3) at which time the Master Trust
will become the active trust. The Class A-3 Investor  Certificates are currently
expected to be repaid by April 1999.

respectively.  Of the $707.9  million,  $100.0 million of Investor  Certificates
were issued to the public and $607.9 million were issued to the 1995 Dealer Note
Master Trust which, in turn, issued $600.0 million to the public. The balance of
